Cell search is one of the key technologies in the WCDMA physical layer. Auxiliary synchronization code sequence identification process is the core of the second phase of cell search. In this paper, a detailed analysis of the auxiliary synchronization code sequence number recognition algorithm, based on this proposed a Fast Hadamard-based FPGA implementation. Hardware and software simulation results show that the program to meet the design requirements. The scheme can be applied to the design of WCDMA cell search module chip
